Description

Die vorliegende Erfindung betrifft einen Steckverbinder gemäß Patentanspruch 1.The present invention relates to a connector according to claim 1.

Die vorliegende Erfindung betrifft daher insbesondere einen Steckverbinder, der mittels eines Haltemittels an einem Gehäuseflansch befestigt ist.The present invention therefore particularly relates to a connector which is fastened by means of a holding means to a housing flange.

Im Stand der Technik ist es üblich, Steckverbinder, insbesondere Buchsensteckverbinder an einem Gerät, einer Gehäusewand oder einem Flansch bzw. über einem Gehäuseflansch mit einem Gehäuse zu verbinden.In the prior art, it is customary to connect connectors, in particular female connectors on a device, a housing wall or a flange or a housing flange with a housing.

In der Regel werden Steckverbinder mit dem Gehäuse mechanisch fest verschraubt.As a rule, plug connectors are mechanically screwed to the housing.

Bei diversen Anwendungen ist es allerdings notwendig, dass der Steckverbinder nicht fest mit einer Gehäusewand verbunden ist, sondern gegenüber der Gehäusewand bewegbar ist, sprich im Gehäuse, beweglich angeordnet ist.In various applications, however, it is necessary that the connector is not fixedly connected to a housing wall, but is movable relative to the housing wall, that is, in the housing, is arranged to be movable.

So ist es z. B. bei Steckverbindern notwendig, bei denen regelmäßig eine Kraft auf das Kabel wirkt, dass der Steckverbinder beispielsweise axial federnd im Gehäuse gelagert wird, so dass bei Zug am Steckverbinder über ein Kabel der Steckverbinder entgegen einer Zug- oder Druckfeder im Gehäuse hin- und her federn kann, ohne dass der Steckverbinder beschädigt wird.So it is z. As in connectors necessary where a force on the cable regularly acts that the connector, for example, axially resiliently mounted in the housing so that when train on the connector via a cable of the connector against a tension or compression spring in the housing back and forth can spring, without the connector is damaged.

Häufig ist es aber weiter notwendig, dass der Steckverbinder auch gegenüber dem Gehäuse abgedichtet ist. Dies wird beispielsweise dadurch bewerkstelligt, dass zwischen dem beweglichen Steckverbindergehäuse und dem Montagegehäuse in dem der Steckverbinder gelagert ist, eine Dichtung vorgesehen ist, gegen die der Steckverbinder mit seinem Gehäuse dichtend anliegt.Often, however, it is further necessary that the connector is sealed against the housing. This is accomplished, for example, that between the movable connector housing and the mounting housing in which the connector is mounted, a seal is provided, against which the connector rests sealingly with its housing.

Wird allerdings der Steckverbinder beispielsweise durch Zug an dem Kabel bewegt, wird dadurch die Dichtung inaktiv bzw. entsteht ein Spalt, durch den Schmutz und Verunreinigungen in das Gehäuseinnere eintreten können.If, however, the connector is moved, for example, by pulling on the cable, this will render the seal inactive or create a gap through which dirt and contaminants can enter the interior of the housing.

Ferner ist von außen nicht ersichtlich, nachdem der Steckverbinder wieder in seine ursprüngliche Position zurückfedert, ob beispielsweise Schmutz auf der Dichtfläche der Dichtung und der Gegendichtfläche anhaftet und daher die Dichtung gänzlich versagt.Furthermore, it is not apparent from the outside after the connector springs back into its original position, for example, if dirt adheres to the sealing surface of the seal and the counter-sealing surface and therefore the seal fails completely.

Insbesondere bei Anwendungen, bei den ein Zugfahrzeug einen Anhänger zieht, kann es vorkommen, dass der Steckverbinder starke Beschleunigungen beim Anfahren des Zugfahrzeuges erfährt und der Steckverbinder übermäßig aus seiner Lagerposition betätigt wird, d. h. axial ausgefedert wird, dass entweder der Steckverbinder beschädigt wird oder Funktionsbeeinträchtigungen zu erwarten sind. Besonders problematisch ist das Anfahren, wenn das Zugfahrzeug mit dem Anhänger zwar elektrisch bereits verbunden ist, aber das Verbinden der mechanischen Hängerkupplung vergessen wurde.In particular, in applications in which a towing vehicle pulls a trailer, it may happen that the connector experiences strong accelerations when starting the towing vehicle and the connector is excessively actuated from its storage position, d. H. is axially rebound that either the connector is damaged or functional impairments are expected. Starting up is especially problematic if the towing vehicle is already electrically connected to the trailer but the connection of the mechanical trailer coupling has been forgotten.

Dann ist es wünschenswert, sofort von Außen zu erkennen, wenn ein solches Ereignis eingetreten ist, dass ggf. mittels einer Wartung oder einer Reparatur der bestimmungsgemäße Zustand wieder hergestellt werden kann.Then it is desirable to recognize immediately from the outside, when such an event has occurred that, if necessary, by means of a maintenance or a repair of the intended condition can be restored.

Vor diesem Hintergrund ist es Aufgabe der vorliegenden Erfindung, vorbesagte Nachteile zu überwinden und einen Steckverbinder bereitzustellen, der gegenüber einem Gehäuse sicher abdichtet, aber bei Eintreten von hohen mechanischen Kräften nicht beschädigt wird und dennoch das Ereignis einer schädigenden mechanischen Einwirkung erkennbar ist.Against this background, it is an object of the present invention to overcome the aforementioned disadvantages and to provide a connector which seals securely against a housing, but is not damaged when high mechanical forces occur and yet the event of a damaging mechanical action is recognizable.

Die vorliegende Aufgabe wird mit den Merkmalen des Patentanspruch 1 gelöst. Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben. In den Rahmen der Erfindung fallen auch sämtliche Kombinationen aus zumindest zwei in der Beschreibung, den Ansprüchen und/oder den Zeichnungen angegebenen Merkmalen. Bei angegebenen Wertebereichen sollen auch innerhalb der genannten Grenzen liegende Werte als Grenzwerte offenbart gelten und in beliebiger Kombination beanspruchbar sein.The present object is solved with the features of claim 1. Advantageous developments of the invention are specified in the subclaims. All combinations of at least two features specified in the description, the claims and / or the drawings also fall within the scope of the invention. For specified value ranges, values lying within the stated limits should also be disclosed as limit values and may be claimed in any combination.

Der Erfindung liegt der Gedanke zu Grunde, den Steckverbinder mit seinem Steckverbindergehäuse über jeweils eine Sollbruchstelle aufweisende Haltemittel an einem Gehäuseflansch bzw. an einem Gehäuse zu befestigen. Hierdurch wird sichergestellt, dass bei ungewollt hohen mechanischen Belastungen des Steckverbinders und damit Kräften oberhalb gewisser Grenzwerte die Haltemittel an der Sollbruchstelle durchtrennt werden. Sofern das Steckverbindergehäuse ferner axial an einer Druckfeder hin- und her bewegbar gelagert ist, wird das Steckverbindergehäuse nach Durchtrennen der Haltemittel an ihrer Sollbruchstelle über die Rückstellkraft der Druckfeder in seine ursprüngliche Lage zurückbewegt.The invention is based on the idea to fasten the connector with its connector housing via holding means each having a predetermined breaking point on a housing flange or on a housing. This ensures that at undesired high mechanical loads of the connector and thus forces above certain limits, the holding means are cut at the predetermined breaking point. If the connector housing is further axially movable back and forth on a compression spring, the connector housing is moved back to its predetermined breaking point on the restoring force of the compression spring in its original position after severing the retaining means.

Auf diese Weise wird sichergestellt, dass das Steckverbindergehäuse nicht beschädigt wird, aber in eine Position in einem Gehäuse oder gegenüber einem Gehäuseflansch gehalten wird, dass es weiterhin funktionsfähig bleibt und ferner anhand der an der Sollbruchstelle durchtrennten Haltemittel unmittelbar erkennbar ist, dass ein den Steckverbinder beeinflussendes oder schädigendes Ereignis eingetreten war.In this way, it is ensured that the connector housing is not damaged, but is held in a position in a housing or a housing flange, that it remains functional and is also immediately recognizable from the cut at the predetermined breaking point holding means that a connector influencing or damaging event had occurred.

Ein Verwender eines solchen Steckverbinders kann also visuell auf einfache Weise erkennen, dass er ggf. den Steckverbinder technisch überprüfen muss und die bestimmungsgemäß "gebrochenen" Haltemittel durch neue Haltemittel ersetzen muss.A user of such a connector can thus visually easily recognize that he must, if necessary, technically check the connector and replace the intended "broken" holding means with new holding means.

Erfindungsgemäß wird daher ein Steckverbinder mit einem Steckverbindergehäuse bereitgestellt, welches mittels einer Druckfeder gegen eine Rückseite eines Gehäuseflansches axial hin- und her bewegbar gelagert wird, wobei Haltemittel vorgesehen sind, mittels derer das Steckverbindergehäuse an der Vorderseite an dem Gehäuseflansch befestigt wird, wobei ferner die Haltemittel einen Befestigungsabschnitt und einen Halteabschnitt aufweisen und zwischen dem Befestigungsabschnitt und dem Halteabschnitt eine Sollbruchstelle angeordnet ist, so dass eine axiale Auslenkung des Steckverbindergehäuses gegenüber dem Gehäuseflansch nur möglich wird bzw. ist, wenn die Halteabschnitt an der Sollbruchstelle durchtrennt wurden.According to the invention, therefore, there is provided a connector having a connector housing which is axially reciprocally movable by means of a compression spring against a rear side of a housing flange, holding means being provided by which the connector housing is secured to the housing flange at the front, further comprising the retaining means a fastening portion and a holding portion and between the mounting portion and the holding portion a predetermined breaking point is arranged, so that an axial deflection of the connector housing relative to the housing flange is only possible or is when the holding portion were cut at the predetermined breaking point.

In einer bevorzugten Ausführungsform der Erfindung kann die Sollbruchstelle in Form einer Nut in dem Haltemittel ausgebildet sein. Auf diese Weise kann ein vorzugsweise in der Dicke gleichmäßiges und auf einer gemeinsamen Ebene angebrachtes Haltemittel verwendet werden, dessen als Sollbruchstelle ausgebildete Nut, vorzugsweise an der Trennstelle zwischen dem Steckverbindergehäuse und dem Gehäuseflansch angeordnet ist.In a preferred embodiment of the invention, the predetermined breaking point may be formed in the form of a groove in the holding means. In this way, a preferably uniform in thickness and mounted on a common plane holding means may be used, which is designed as a predetermined breaking point groove, preferably disposed at the separation point between the connector housing and the housing flange.

In einer weiter bevorzugten Ausführungsform weist das Steckverbindergehäuse einen ringförmigen Befestigungsabsatz auf, gegen denen die Halteabschnitte des Haltemittels anliegen.In a further preferred embodiment, the connector housing has an annular attachment paragraph, against which abut the holding portions of the holding means.

Auf diese Weise kann sichergestellt werden, dass der Befestigungsabschnitt am Gehäuseflansch aufliegt, während der Halteabschnitt auf dem Befestigungsabsatzes des Steckverbindergehäuses aufliegt und sich die dazwischenliegende Sollbruchstelle (vorzugsweise der dazwischenliegende als Nut ausgebildete Sollbruchstelle) fluchtend über der Trennstelle zwischen Steckverbindergehäuse und Gehäuseflansch befindet.In this way it can be ensured that the attachment portion rests on the housing flange, while the holding portion rests on the attachment paragraph of the connector housing and the intermediate predetermined breaking point (preferably the intermediate designed as a groove breaking point) is aligned over the separation point between the connector housing and housing flange.

In einer weiter bevorzugten Ausführungsform sind die Haltemittel so ausgebildet, dass benachbart zur Sollbruchstelle eine Ausnehmung in wenigstens einem vorzugsweise allen der Haltemittel als Verdrehschutzmittel ausgebildet ist bzw. sind. Hierdurch kann sichergestellt werden, dass das gegenüber dem Gehäuseflansch beweglich gelagerten, jedoch in seiner Position fixierte Steckverbindergehäuse in seiner Lage in Rotationsrichtung nicht unbeabsichtigt verdreht wird.In a further preferred embodiment, the holding means are formed so that adjacent to the predetermined breaking point a recess in at least one preferably all of the holding means is designed as anti-rotation means or are. This makes it possible to ensure that the connector housing, which is movably mounted relative to the housing flange but is fixed in its position, is not unintentionally rotated in its position in the direction of rotation.

Es ist ferner bevorzugt, benachbart zur Sollbruchstelle eine Ausnehmung so auszubilden, dass diese in eine am Steckverbindergehäuse angeordnete korrespondierende Nut eingreift.It is further preferred, adjacent to the predetermined breaking point form a recess so that it engages in a corresponding groove arranged on the connector housing.

Als weitere Maßnahme zur Sicherung der Position und/oder des Verdrehschutzes können am Gehäuseflansch eine oder mehrere Anschlagrippen für die Haltemittel benachbart zu diesen so angeordnet werden, dass die Haltemittel gegen ein Verdrehen gegenüber dem Gehäuseflansch gesichert werden und eine definierte Position zum Einbringen der Haltemittel gegeben ist.As a further measure to secure the position and / or the anti-rotation may be arranged on the housing flange one or more stop ribs for the holding means adjacent thereto so that the holding means are secured against rotation relative to the housing flange and a defined position for introducing the holding means is given ,

In einer weiter bevorzugten Ausführungsform verfügen die Haltemittel in ihren Befestigungsabschnitten über eine Befestigungsöffnung. Auf diese Weise kann mittels des Haltemittels der Befestigungsabschnitt am Gehäuseflansch verschraubt werden, während der Halteabschnitt den Befestigungsabsatz klemmend gegen die Kraft der Druckfeder lagert.In a further preferred embodiment, the holding means have a fastening opening in their attachment sections. In this way, by means of the holding means, the fastening portion can be screwed to the housing flange, while the holding portion supports the fastening paragraph by clamping against the force of the compression spring.

In einer weiter bevorzugten Ausführungsform ist die Sollbruchstelle bogenförmig ausgebildet, wobei der Radius, d. h. der Bogenradius der Sollbruchstelle dem Radius des Steckverbindergehäuses im Bereich des ringförmigen Befestigungsabschnittes entspricht. Auf diese Weise kann die bogenförmige Sollbruchstelle fluchtend mit der Außenkontur des ringförmigen Befestigungsabschnittes angeordnet werden.In a further preferred embodiment, the predetermined breaking point is formed arcuate, wherein the radius, ie the radius of curvature of the predetermined breaking point corresponds to the radius of the connector housing in the region of the annular fastening portion. In this way, the arcuate predetermined breaking point can be arranged in alignment with the outer contour of the annular attachment portion.

Auf diese Weise wird sichergestellt, dass bei axialem Zug mit einer Kraft oberhalb eines definierten Wertes, die die Haltemittel an ihrer Sollbruchstelle durchtrennen lässt, wobei die Kraft exakt an der Sollbruchstelle eingeleitet wird, da sich die Sollbruchstelle fluchtend in der Bewegungsachse des Steckverbindergehäuses befindet.In this way it is ensured that in axial tension with a force above a defined value, which can cut through the holding means at its predetermined breaking point, wherein the force is introduced exactly at the predetermined breaking point, since the predetermined breaking point is aligned in the axis of movement of the connector housing.

In einer besonders bevorzugten Ausführungsform ist die Materialdicke im Bereich der Sollbruchstelle etwa 5 % bis 40 % der Materialstärke im Bereich des Halteabschnittes.In a particularly preferred embodiment, the material thickness in the region of the predetermined breaking point is about 5% to 40% of the material thickness in the region of the holding section.

In einer weiter bevorzugten Ausführungsform entspricht die Materialdicke im Bereich der Sollbruchstelle etwa 5 % bis 20 % der Materialstärke im Vergleich zu der Materialstärke im Bereich des Halteabschnittes.In a further preferred embodiment, the material thickness in the region of the predetermined breaking point corresponds to about 5% to 20% of the material thickness in comparison to the material thickness in the region of the holding section.

In einer weiter bevorzugten Ausführungsform ist die Materialstärke im Bereich des Halteabschnittes identisch mit der Materialstärke im Bereich des Befestigungsabschnittes.In a further preferred embodiment, the material thickness in the region of the holding section is identical to the material thickness in the region of the fastening section.

Auf diese Weise kann sichergestellt werden, dass die Stabilität der Haltemittel ausschließlich über die Dicke und Materialstärke der Sollbruchstelle bestimmt wird, während die Stabilität und Festigkeit der Haltemittel im Bereich des Halteabschnittes und des Befestigungsabschnittes ausreichend hoch ist.In this way it can be ensured that the stability of the holding means is determined solely by the thickness and material thickness of the predetermined breaking point, while the stability and strength of the holding means in the region of the holding portion and the fixing portion is sufficiently high.

Entsprechend den zu erwartenden auftretenden mechanischen Einflüssen kann daher der Auslösemechanismus zum Durchtrennen der Sollbruchstelle abhängig von der Materialstärke in der Sollbruchstelle bestimmt werden.In accordance with the mechanical influences which are to be expected, therefore, the triggering mechanism for severing the predetermined breaking point can be determined depending on the material thickness in the predetermined breaking point.

In dieser Hinsicht können mittels des erfindungsgemäßen Steckverbinders eine Vielzahl unterschiedlicher Applikationen mit unterschiedlich auftretenden und zu erwartenden Kräfte abgebildet werden, bei dem sichergestellt wird, dass bei Auftreten solcher mechanischer Einwirkungen der Steckverbinder bis auf die Haltemittel nicht beschädigt wird.In this regard, by means of the connector according to the invention a variety of different applications with different occurring and expected forces can be mapped, which ensures that is not damaged in the occurrence of such mechanical effects of the connector to the holding means.

Ferner ist optisch unmittelbar erkennbar, dass bei Brechen der Haltemittel an den Sollbruchstellen ein entsprechendes Ereignis eingetreten war.Furthermore, it is visually immediately recognizable that a corresponding event had occurred when breaking the holding means at the predetermined breaking points.

Der Verwender des erfindungsgemäßen Steckverbinders kann daher ohne großen Aufwand den Steckverbinder reparieren, indem er die Haltemittel austauscht und gleichzeitig untersuchen, ob der Steckverbinder möglicherweise in folge des Ereignisses beschädigt wurde.The user of the connector according to the invention can therefore easily repair the connector by exchanging the retaining means and at the same time investigating whether the connector has possibly been damaged as a result of the event.

In den Figuren 1 und 2 ist ein erfindungsgemäßer Steckverbinder 1 gezeigt. Der Steckverbinder 1 verfügt über ein Steckverbindergehäuse 10, das an einer Druckfeder 4 gegen eine Rückseite 5a eines Gehäuseflansches 5 gelagert ist. Der Gehäuseflansch 5 weist Befestigungsöffnungen 50 an seinen Ecken auf. Die Befestigungsöffnungen 50 erstrecken sich von der Vorderseite 5b zur Rückseite 5a des Gehäuseflansches 5. Das Steckverbindergehäuse 10 verfügt über einen ringförmigen Befestigungsabsatz 11. Der Gehäuseflansch 5 verfügt ferner über eine ringförmige Öffnung 51, durch die sich der Steckverbinder hindurch mit seinem Steckverbindergehäuse 10 erstreckt, wobei der ringförmige Befestigungsabsatz 11 mit seiner vorderen Oberfläche 12 mit der Vorderseite 5b des Gehäuseflansches 5 in einer gemeinsamen Ebene liegt. Zwischen dem Befestigungsabsatz 11 und der Öffnung 51 des Gehäuseflansches 5 befindet sich eine Radialdichtung, die das Steckverbindergehäuse 10 gegenüber dem Gehäuseflansch 5 radial abdichtet. Das Steckverbindergehäuse 10 ist mittels Haltemittel 2 am Gehäuseflansch 5 befestigt. Sobald das Steckverbindergehäuse 10 mittels der Haltemittel 2 am Gehäuseflansch 5 befestigt ist, lässt sich der Steckverbinder 1, d. h. das Steckverbindergehäuse 10 nicht mehr in axialer Richtung der Wirkung der Rückstellkraft herausziehen.In the FIGS. 1 and 2 an inventive connector 1 is shown. The connector 1 has a connector housing 10 which is mounted on a compression spring 4 against a rear side 5a of a housing flange 5. The housing flange 5 has attachment openings 50 at its corners. The mounting holes 50 extend from the front 5b to the back 5a of the housing flange 5. The connector housing 10 has an annular mounting shoulder 11. The housing flange 5 also has an annular opening 51 through which the connector extends with its connector housing 10, wherein the annular attachment paragraph 11 lies with its front surface 12 with the front side 5b of the housing flange 5 in a common plane. Between the fastening shoulder 11 and the opening 51 of the housing flange 5 there is a radial seal, which radially seals the connector housing 10 relative to the housing flange 5. The connector housing 10 is secured by means of retaining means 2 on the housing flange 5. Once the connector housing 10 is secured by means of the retaining means 2 on the housing flange 5, the connector 1, ie the connector housing 10 can no longer pull out in the axial direction of the action of the restoring force.

Die in Fig. 1 gezeigten Haltemittel 2 werden In Fig. 2 im Detail dargestellt.In the Fig. 1 shown holding means 2 are In Fig. 2 shown in detail.

Die Haltemittel 2 verfügen über einen Befestigungsabschnitt 22 und einen Halteabschnitt 21, wobei zwischen dem Befestigungsabschnitt 22 und dem Halteabschnitt 21 eine bogenförmige Sollbruchstelle 20 in Form einer Nut angebracht ist. Benachbart zur Sollbruchstelle 20 ist eine Ausnehmung 23 vorgesehen. Die Ausnehmung 23 greift in die im Detail A erkennbare korrespondierende Kontur 12 ein. Die Kontur 12 entspricht in ihrer Form der Ausnehmung 23 und ragt aus der Stirnfläche des Befestigungsabsatzes 11 heraus.The holding means 2 have a fixing portion 22 and a holding portion 21, wherein between the fixing portion 22 and the holding portion 21, an arcuate predetermined breaking point 20 is mounted in the form of a groove. Adjacent to the predetermined breaking point 20, a recess 23 is provided. The recess 23 engages in the recognizable in detail A corresponding contour 12 a. The contour 12 corresponds in shape to the recess 23 and protrudes from the end face of the fastening paragraph 11 out.

Im Detail A der Fig. 1 ist ferner ersichtlich, dass jeweils zwei Anschlagrippen 3 eine Auflagefläche für das Haltemittel 2 begrenzen.In detail A the Fig. 1 It can also be seen that in each case two stop ribs 3 delimit a support surface for the holding means 2.

Dabei liegen die Seitenkanten 25 des Haltemittels 2 gegen die Innenflanken der Anschlagrippen 3 an. Dies sichert einen weiteren Verdrehschutz des Steckverbindergehäuses 10 gegen Verdrehen gegenüber dem Gehäuseflansch 5.In this case, the side edges 25 of the holding means 2 bear against the inner edges of the stop ribs 3. This ensures a further rotation protection of the connector housing 10 against rotation relative to the housing flange 5.

Die Haltemittel 2 sind mit ihrer Ausnehmung 23, welche Ausrichtmittel darstellen, so angeordnet, dass die Sollbruchstelle 20 mit der Trennstelle (bzw. Spalt) zwischen dem Steckverbindergehäuse 10 bzw. dem ringförmigen Befestigungsabsatz 11 und der Öffnung 51 des Gehäuseflansches 5 fluchtet.The holding means 2 are arranged with their recess 23, which are alignment means, so that the predetermined breaking point 20 with the separation point (or gap) between the connector housing 10 and the annular mounting shoulder 11 and the opening 51 of the housing flange 5 is aligned.

Wie in Fig. 2 ersichtlich, beträgt die Materialstärke im Bereich der Sollbruchstelle etwa 10 % der Materialstärke im Bereich des daneben liegenden Halteabschnittes 21 sowie ferner im Bereich des Befestigungsabschnittes 22.As in Fig. 2 As can be seen, the material thickness in the region of the predetermined breaking point amounts to approximately 10% of the material thickness in the region of the adjacent holding section 21 and also in the region of the fastening section 22.

Die Haftemittel 2 sind in dem vorliegenden Ausführungsbeispiel mit dem Gehäuseflansch 5 verschraubt. Bevorzugt kann die Rückseite 5a des Gehäuseflansches 5 auch planeben und geschlossen ausgebildet sein, um eine stirnseitige Dichtung aufzubringen, um dieses an einer entsprechenden Gehäuseöffnung eines Gehäuses zu verschrauben.The adhesive 2 are bolted to the housing flange 5 in the present embodiment. Preferably, the rear side 5a of the housing flange 5 may also be designed level and closed in order to apply a front-side seal in order to screw it to a corresponding housing opening of a housing.

Wird an dem erfindungsgemäßen Steckverbinder 1 z. B. mittels massivem, axialem Zug gezogen, z. B. bei beschleunigtem Anfahren eines Zugfahrzeuges, bei dem vergessen wurde, den Anhänger anzukuppeln, so wird eine entsprechende Zugkraft über den korrespondierenden Gegenstecker auf den erfindungsgemäßen Steckverbinder 1 übertragen und der Steckverbinder 1 aus seiner Montageposition herausgerissen, während die Haltemittel 2 an ihrer Sollbruchstelle 20 durchtrennt werden.Is at the connector 1 according to the invention z. B. pulled by means of solid, axial train, z. As in accelerated startup of a towing vehicle, in which was forgotten to couple the trailer, a corresponding tensile force on the corresponding mating connector is transmitted to the connector 1 according to the invention and the connector 1 torn from its mounting position, while the holding means 2 severed at its predetermined breaking point 20 become.

Nach dem Durchbrechen bzw. Durchtrennen der Sollbruchstellen 20 wird der Steckverbinder 1 axial gegen die Druckfeder bewegt, so lange, bis der Gegenstecker aus der Steckverbindung abgezogen ist. Auf diese Weise können Beschädigungen am Steckverbinder 1 weitgehenst vermieden werden. Die Reparatur danach gestaltet sich denkbar einfach, in dem die defekten Haltemittel 2 ausgetauscht werden und der Steckverbinder in seine ursprüngliche Montageposition mittels neuer Haltemittel gebracht wird.After breaking through or cutting through the predetermined breaking points 20, the connector 1 is moved axially against the compression spring, until the mating connector is removed from the connector. In this way damage to the connector 1 weitgehenst be avoided. The repair after that is very simple, in which the defective retaining means 2 are replaced and the connector is brought into its original mounting position by means of new retaining means.
